Comparison
ai-gateway vs openinfer
Verdict
Pick ai-gateway if ai-gateway from Ferro Labs supports over 30 LLMs with integrated caching, guardrails, A/B testing, and cost controls, making it ideal for managing multiple language models in a production environment; pick openinfer if high-performance GPU-based inference engine for Rust developers targeting Qwen3 and Kimi-K2 using pure CUDA kernels.

Choose ai-gateway if…
- ai-gateway is primarily Go; openinfer is Rust.
- Tags unique to ai-gateway: ai-gateway, litellm, llm-cost, llm-proxy.
- Also covers Model Training.
- When you need to integrate more than 30 different LLM services including OpenAI and Anthropic
When NOT to use ai-gateway
- If your project only involves one or two LLMs which does not necessitate the gateway's broad compatibility features
- For small-scale projects that do not require comprehensive cost analysis tools
- When custom integration for specific guardrails is required, as ai-gateway offers generalized settings
Choose openinfer if…
- openinfer is primarily Rust; ai-gateway is Go.
- Tags unique to openinfer: cuda, gpu, llm-inference, openai-api.
- When you are working with large language models Qwen3 and/or Kimi-K2 specifically, and want to avoid PyTorch dependencies.
When NOT to use openinfer
- Avoid if you are developing models other than Qwen3 or Kimi-K2 as support for other models might be limited.
- Not recommended for projects where PyTorch integration is crucial as this tool does not depend on it and may require changes in existing workflows.
